I am not producing this book for a living, but the people at Manning do. If you still think that you don't want to buy a printed or e-paper version and are satisfied by using the public version, you're welcome to do so.

You could still think of contributing a little bit, either by volunteering to

• your favorite software project
• a software industry improvement project
• a free speech or publication project
• the national C standards committee of your country

or anything else that makes the whole world (or maybe just our planet) a better place.

You could also contribute by giving whatever money you may spare to such a project. There are many projects in need of contributions, not all important open source projects out there are financed by big money, and that independence is important.

The musl libc project has had my attention for several years now:

I find such a C library project aiming to be standard conforming (C and POSIX) particular helpful. Their C sources are a treasure trove if your are looking into simple but efficient code. As an extra plus, this is a project with a really humane discussion culture, a proof that people (even men!) can constructively work together to achieve great things without denigrating each other.
